Specs: XP Pro, 4GB RAM, 8800GTX, Audigy 4. Latest drivers all around, Windows completely patched up. When gaining or loosing focus Sins now locks up the computer for 2-5 seconds. Before 1.02, alt-tabbing into and out of Sins was basically instant. I've tried both full-screen and windowed mode and both have this issue.
As a side note, please have the game remember the position and screen size when restarting in windowed mode. It's annoying having to resize the game every time I start it.
Thanks.
